John was always a bit of a short tempered man. He had issues with with controlling his anger, and often found himself acting on instincts before even thinking about them. And if you couple this with the fact that he wasn't exactly human... well, things didn't end well.

So when you found him on the outskirts of camp, hands and face covered in blood, while he was supposed to be on guard duty, you weren't all too surprised. He avoided your eyes with a guilty look on his face, ears pinned back and tail wagging nervously. He looked like a guilty dog who had done something it knew it shouldn't have. You couldn't even find the poor soul that fell victim to him.
